Control register. Each DAC has two bits to control the

Power-Down state of the DAC. This register is for both

volatile and nonvolatile memory locations.

PDnB:PDnA: DAC Power-Down Control(2)

11 = Powered down – VOUT is open circuit

10 = Powered down – VOUT is loaded with a 125 k resistor to ground

01 = Powered down – VOUT is loaded with a 1 k resistor to ground

00 = Normal operation (not powered down)

Note 1:

Unimplemented bit, read as ‘0’.
